A criterion of containment for tropical hypersurfaces

Algebraic Geometry 2024-03-04 v2

Abstract

For tropical nn-variable polynomials f,gf, g a criterion of containment for tropical hypersurfaces Trop(f)Trop(g)Trop(f)\subset Trop(g) is provided in terms of their Newton polyhedra N(f),N(g)Rn+1N(f), N(g)\subset \mathbb{R}^{n+1}. Namely, Trop(f)Trop(g)Trop(f)\subset Trop(g) iff for every vertex vv of N(g)N(g) there exist a homothety tN(f),t>0t\cdot N(f), t>0 and a parallel shift s:Rn+1Rn+1s:\mathbb{R}^{n+1} \to \mathbb{R}^{n+1} such that vs(tN(f))N(g)v\in s(t\cdot N(f))\subset N(g).
